Abstract
This paper makes reference lo the analysis ofstructural reforms made in Latin America and the Caribbean in the years 1990 - 2000 and their effects in the Social Security Systems adopted in eachcountry. The analysis determines trough econometric model of panel, how reforms in the life quality (life expectancy, infant mortality rate)influence vis-a-vis macroeconomic variables like theGross domestic product and employment. These models show that though Latin America and theCaribbean, start from the same (contributive and joint regulation) assurance principies, variables' behavior do not answer the expectations in the assurance and health services for everybody in 2000.
